running board structure and has for an object the securing of the roofing sheets to the car without the use of nails. A further object is the provision of a securing means of the nature referred to in which the joint between the roofing sheets is made weathertight and yet sufficiently flexible to allow for weaving action of the car in use. A further object of the invention is the provision of means for holding the running board saddle {to the car roof without the use of holding means which project through the car roof. A further object of the invention 'is the provision of car roof holding means which protect theheads of the bolts whichsecure its anchor to the car body plate. p In the accompanying drawings, I Figure 1 is a plan view of one end of the car roof,

I Fig. 2 is a side view of a portion of the oar roof, partially in longitudinal section,

, Fig. 3 is a transverse section On line 3--8 of Fig. 1, I V I Fig. 4 is a sideview of the car roof showing the end of one of the holding plates,

Fig. 5 is a transverse section on line 55 of Fig. 4,

Fig. 6 is a section correspondingto Fig. 5, but showing a modification, and

Fig. 7 is a section on anenlarged scale,

showing the roofing oint and holding plate. The car roof frame comprises the usual carline 1, ridge pole 2, plate 3, fascia4, roof boards 6. 5 designates the siding ofthe car. Purlins, not shown, may be used if desired.

The ear roof covering sheets, indicated at I 7, consist of sheets preferably of metal, having at eachmargin one or more corrugations, three corrugations being shown in the drawings. When in place upon the car roof these corrugated margins are overlapped, the corrugations mating together. The sheets preferably extend from one edge to the other of the roof and are downturned over the fascia.

Holding plates 8 are corrugated to conform to the configuration of the margin of the overlying roofing sheet at each joint and are superimposed thereon. These holding plates are'substantially continuous from one edge of the roof to the other, and means are shown for placing the holding plates under tension whereby they are caused to bear down upon the overlapped edges of the roofing sheets. If the holding plate is continuous from one edge of the roof to the other the meansof securing the end of the holding plate, shown in Fig. 6, as a bracket 9, secured to the fascia by bolt 10, and a second bracket 11, secured to the holding plate by rivet 12, will result in the tightening of the holding plate when the bolt 13 connecting said brackets has its nut screwed down, the tightening of which will put strain upon the holding plate. i

Preferably, however, I use the anchoring plate shown at 14 (Fig. 5) which anchoring plate is secured to the fascia by bolts 10' pass ing through the anchoring plate, the fascia, and the car body plate. Anchor plate 1 1 has a hook 15 formed thereon near its bottom edge and holding plate'8 has an eye 16 suitable for engagement over said hook. The eye 16" is formed in the downturned'end 16 of the holding plate and it will be observed that the arrangement of the parts, as shown in Figs. 4 and 5, will result in the effectual covering of the heads of the bolts 10 thereby protecting them from the weather, preventing their loss should their nuts become loosened and furthermore, preventing water from fiowingin through the hole through which the bolt is passed. In this modification the holding plates areplaced under tension by means of a bolt 17 passing through the upstanding portions of brackets 18, 18, riveted to the ridge end of the holding plates by rivets, as 19. When the bolt is To allow brackets 18 to project into the interior of the saddle, the saddle is cut away at the central port-ion of its bottom wall, as indicatedat 2 A bolt 25 is passed transversely through the walls of the saddle and under bolt 17 whereby the bolt 17, firmly held to the roof bybrackets 18 and holding plates 8, will preventthe saddle from lift- 111g. Running boardenembersiilti arebolted or riveted to theupper wall of the running board saddle. The peculiar arrangement of the running board sadd'leand the brackets 18 result in protecting these brackets and their: connections with the holding plates from the weather.-

If desired the corrugations in the holding plates mav be made slightly deeper than thosein the margins of the roofing sheets and-\as aresult thereof the-edges oi the hold- .ing pla'tesand also thebottom' of the corrugations :oi the same will cause pressure to be place'd upon the roofing sheets at those 'pointsnea-rest" to the roofing-boards.

This

. will result in tighter edges 'wherethe elements seek to find entrance, and abetter joint) between the I roofing sheets. Moreover, the edge otthe holding plate adjacent the edge of the roofing sheet which is on: top

may beextended beyondwthe same and bent downward to -contact'with the underlying roofing a sheet thereby protecting the point of 's rreatest vulnerability of the joint.

The'corrugations at one edge of each sheet may bemade slightly more shallow and less abrupt of curvature than thoseat the other margin of the same sheet'which arrangement will result in increased flexibility of joint. This will result in a relation of parts asindicated in Fig. 7, wherein the more shallowand less abruptly curved corrugations of one sheet are shown as overlapped by the deeper and more pointed corrugations of the-next sheet, producingspaces as 27 betweenthe crests. of the corrugations allowing relative movement between the respectiie-sheets while maintaining the integrit-y of the joints andot the bodyof the sheets.

The same-result may be attained byproviding alternate sheets with identical corrugations -on their two margins but differing from the corrugations upon the remainder in-which case alternate sheets will have both their margins underlying and alternate sheets-will have both their margins overlying, contiguous sheets.

I claim as my invention:

1,- A can roofcovering comprising roofing plates provided with overlapping corrugated margins, a corrugated holding plate covering and mating with said corrugated margins and ineansacting on said plate in an endwise direction to tension the same.

2. A car roof covering comprising sheets extending transversely of the car roof with their margins overlapping, aholdi-ng plate of a width corresponding with said overlap, means to anchor said plate at each edge of the. roof andmeans endwise applied- -for tensioning said plate; V
